johnc Posted June 20, 2002 Share Posted June 20, 2002 Build a heat shield out of the thickest aluminum you can bend. Your intake will thank you for it. Quote Link to comment Share on other sites More sharing options...
DAW Posted June 21, 2002 Share Posted June 21, 2002 The header wrap helps a lot! Try touching your hand to the exhaust header/manifold under the intake manifold with wrap vs without. (Don't really do it; the reduction in heat radiation with the wrap is immense). DAW Quote Link to comment Share on other sites More sharing options...

scottyMIz Posted June 21, 2002 Author Share Posted June 21, 2002 thanks guys i don't have alot of room for a heat sheild plus i like being able to see the exhaust manifold so if i have to take it off it's easier to get to the bolts.I'm gonna get some of that wrap either today or tomorrow cuz this weekend is dedicated to my z I'm gonna change the oil hook up the boost controller and wrap the manifold.Then i'll turn the boost up and see what she'll do.

Lockjaw Posted June 21, 2002 Share Posted June 21, 2002 Don't get to happy with the boost. I don't want to hear any bad news when I come back to work monday. I would like to know how well you think the header wrap works since I never have run a heat shield between my turbo and intake manifold. Makes me wonder what I could have run. I hope you get some improved performance. You should see some pretty healthy gains. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted June 21, 2002 Share Posted June 21, 2002 Scotty, I assume you are wanting to wrap the exhaust manifold. Header wrap works great and I can actually hold my DP with the car idling. HOWEVER, I would not recommend putting header wrap on anything but stainless steel. Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted June 21, 2002 Author Share Posted June 21, 2002 does the wrap melt on the regular steel scottie?I just want to get the temps down and i have evry limited space for heat sheilds.I was thinking a hood vent/scoop or something like that but i like the smooth look with out the vents.Anyone else got any ideas?

scottyMIz Posted June 21, 2002 Author Share Posted June 21, 2002 well i got a roll for 25 bucks today i guess if it rots out then i'll just have to make a turbo header Thanks for the heads up scottie maybe i can do something to release the moisture.....

Guest Tom Scala Posted June 21, 2002 Share Posted June 21, 2002 I don't think the wrap would do any damage to a cast iron manifold,at least not for a very long time. Tube headers definetly yes. I wrapped a new set of Hedman headers on a 455 Firebird once and they rotted from the inside out in a matter of months. Blew a hole the size of a half dollar out. The pipes looked good from the outside but were soft to the touch. Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted June 22, 2002 Author Share Posted June 22, 2002 ok guys have the wrap on and it helps ALOT i can actually put my hand on the intake without screaming Well unless i feel like screaming BUt it does help alot especially on the turbo it make the ic pipe coming from the turbo MUCH cooler and i changed the oil and turned the boost up sofar it will only hit 16 or so but man does it haul a$$ i have to mess with it tomorrow to find out why it's not hitting 20psi maybe the hose is crimped somewhere and stopping me from the potential it's capable of.But as it is now at 16 psi it will break the tires loose bad in first and second before it would just slide a little now it squeals and just slamms to the side a real fun ride I love the new turbo Quote Link to comment Share on other sites More sharing options...
Guest Tom Scala Posted June 22, 2002 Share Posted June 22, 2002 I took off the funky heat shield that comes on the exhaust manifold and wrapped it with ThermoTech header wrap. The steel heat shield doesn't insulate nearly as well as this stuff. You can put your hand on the manifold when the engine is runing and it gives you more room to run a larger compressor without having to use a spacer. Highly recomended Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted June 22, 2002 Share Posted June 22, 2002 Moisture gets trapped under the wrap that will eventually affect regular steel. Lots of headers have gone to the scrap as a result of folks unknowing. Quote Link to comment Share on other sites More sharing options...
